“Embarking on the Mission Hill Yoga teacher training journey has been nothing short of transformative! Cassi’s deep understanding of yoga, combined with her teaching style, creates an environment where growth and self-discovery flourish.

Cassi’s passion for yoga is contagious, and her guidance goes beyond just mastering poses; it extends to cultivating mindfulness, compassion, and authenticity both on and off the mat. Throughout the training, she fosters a supportive community where each student feels seen, heard, and empowered to embrace their unique journey.

Thanks to Cassi’s dedication and expertise, I not only gained the knowledge and skills to become a certified yoga teacher, but I also discovered a deeper connection to myself and a profound sense of inner peace. I am forever grateful for the invaluable experience of learning and growing under her guidance.

I encourage any yogi who may be on fence about embarking on their own YTT journey to take the leap of faith - I promise, you won’t regret it. Thank you Cassi! ”

“No matter where your interest in yoga stems from, you will get everything you want and much more from Cassi’s 200 hour teacher training. Her ability to give such a personalized experience in a group setting makes this training stand out, and she ensures that every student is heard, learning, and growing. You’re able to learn about all different aspects of yoga, including history, meditation, physical practice, assisting, business, and many other things that make yoga so much more than just a workout. You’re also able to dive deeper and focus on the aspects that most closely resonate with you, and begin to discover what type of teacher you may want to be. Cassi is such a helpful teacher throughout the whole process, and the community of past and present students that she builds is unlike anything you’ll find anywhere else. No matter what you’re looking for, I cannot recommend this training enough! ”

“I found yoga about 7 years ago and my practice has been a reliable companion through all of lifes ups and downs. I knew early on in my journey that I wanted to share the gift of yoga with others. After many years of fear-driven excuses, I finally convinced myself to go for it. I googled “yoga teacher training near me” and discovered Mission Hill Yoga. I had never practiced there before but after an informative chat with Cassi, I knew I found a good fit and signed up immediately. I was a stranger to the studio but it never felt that way!

Cassandra’s obvious passion for yoga and deep knowledge of yogic principles is truly inspiring. Her positive attitude and upbeat personality gives way to the awesome energy in the studio.

Cassi leads a training that delves deep into all of the aspects of yoga. The course layout allows for plenty of time to study and integrate the new information before moving on to the next topic. I especially appreciated having just three fellow trainees in the group. The small class size allowed for plenty of time for questions and discussion. I have been sincerely moved by the philosophy of the practice I hold so dear. Bringing this ancient wisdom into my daily life has made a world of difference. Discovering all of the intricacies within the poses has been amazing but I feel more like my physical practice has changed from the inside out.

This course challenged me in a way that I had never been challenged before. I started so far out of my comfort zone but Cassi, along with my fellow trainees, has facilitated such a safe and supportive environment. It was this factor that allowed for the vulnerability to open up the space for me to expand and grow. Not only did I learn how to effectively lead a yoga class, I gained the confidence to do so. I will be forever grateful to Cassi and the teaching community at Mission Hill Yoga. ”

“If you are interested in taking your yoga practice to the next level, I highly recommend Cassandra’s yoga teacher training. You will learn about the spiritual foundations of yoga, Buddhism, and anatomy. You will also learn how to perfect poses, and create a vinyasa sequence all your own. Most of all you will learn how to share your knowledge of yoga to help others. Taking this training was a wonderful experience. Cassandra is a helpful and understand teacher and your classmates will likely become good friends as you go on this journey together”

“Wow, where to even begin. Yoga Teacher training at MHY has been a truly life-changing experience. Initially, I was nervous about the whole process, but very quickly realized that it was all about self-development. It’s hard to articulate, but the amount of growth I have felt & experienced within the YTT training is unparalleled to anything I have done before. Giving yourself the space to blossom into a teacher is something truly unique. The various training weekends introduced me to new ways of thinking, as well as new ways to look at the world. It would be an understatement to say that teacher training changed my outlook on yoga because it changed my perspective on the world. This was done through the variety of readings we did, as well as listening to Cassi’s first-hand accounts of what it is like to be a yoga instructor in these trying times. Her introspection is realistic and she offers practical advice to anyone looking to teach yoga in the near future. Not to mention that her kindness and authenticity take away all the “nervousness” that might come along with learning a new skill. Learning and growing within a small group of like-minded individuals allowed me to overcome my previous fears. Again, I can’t fully articulate how special this teacher training is, but rather it is something one has to experience for themselves in order to fully understand. To anyone looking to further their own journey, whether that be spiritually, mentally, or physically, I can’t recommend this path enough.”

“The 200hr yoga teacher training at Mission Hill Yoga was a completely transformative experience. After practicing regularly for about 3 years, I decided to deepen my practice further. Cassi created a safe and welcoming learning environment and gave me all the tools and knowledge I needed to take my practice to the next level. She is a phenomenal teacher who takes great pride in her work. Cassandra fosters an environment that values creativity and fun while also emphasizing hard work and stepping outside your comfort zone in order to learn and grow. In the beginning, I imagined myself teaching yoga to friends and family, but I never planned to formally teach. However, after completing MHY’s teacher training, I feel totally prepared to teach in any setting. I am so grateful to Cassi for creating such an outstanding experience, and I cannot recommend her teacher training highly enough.”

“I truly believe Yoga Teacher Training at MHY has changed my life and has helped me grow as a person. Most of my life, I have given to everyone around me, and deciding to do teacher training was the first time I was putting myself first. When I was first debating enrolling in teacher training, I was worried that it might push me over the edge, because I was working at a very demanding job and at the time was applying to grad school… but I finally took the leap of faith and every teacher training weekend that came around, I couldn’t help but think to myself, “wow, I really need this”. Comprehensively you will the basic foundations of the poses, dharma and anatomy. Additionally, and as a great surprise to myself, you will also begin a journey of your own self-discovery, feel the pure bliss of learning assisting, gain a feeling of being connected to the yoga community, and deepen your own self practice. Cassi always created a safe, welcoming and real environment. She always took all of interests into account as an opportunity to foster a space that was filled with unconditional support, creativity and fun. I not only feel prepared to teach in any setting, but I also have gained a sense of confidence and peace within myself. I would recommend this teacher training to anyone wanting to teach full time, part time, or someone who is looking to deepen their own practice! Cassi – I am so grateful to you and all that you do!!”

“MHY’s Yoga Teacher Training exceeded all of my expectations. The training is intensive and well-rounded, focusing on many different topics such as the history of yoga, meditation, self-practice, and hands-on adjustments and assisting. Cassi is a supportive and knowledgeable teacher, and her feedback throughout the training was thoughtful and incredibly helpful. I was unsure at the beginning of this experience if I wanted to teach yoga and joined the teacher training hoping to deepen my self-practice and learn more about the origins of yoga. As the months in the training progressed, I felt my confidence and interest in teaching grow, and I was surprised to find by the end that I felt completely prepared and excited to teach yoga. This teacher training has been a life-changing journey, and I would not have wanted to complete it anywhere else. Cassi has helped create a close-knit community of yoga teachers and students at MHY, and I am deeply grateful to have stumbled across this studio three years ago. Thank you so much Cassi and my fellow teacher trainees for making this experience everything that it was. If you are considering completing a yoga teacher training, you will get everything you need and more from MHY!”

“I learned so much about yoga and about myself in Cassandra’s teacher training class. Cassandra is a truly exceptional teacher and person, and these qualities are clearly reflected in the yoga community that gathers around her.
I also want to thank Cassi for the thoroughness and care of the Covid protections applied to both class protocols and the studio’s physical space. It felt like a secure place to practice at all times.”

“I attended Mission Hill Yoga’s 200 hour teacher training class that began in early 2021. I have been practicing yoga for approximately 10 years and decided to use the teacher training as a way of deepening my understanding of yoga and to further develop my practice. I had no real intention of ever teaching yoga. During the first few sessions of the training, I learned so much about the origins and various schools of yoga, meditation techniques, types of pranayama, and other topics that I had always been curious about. As we began learning how to teach yoga, I began to realize that I enjoyed teaching more than I thought I would. Cassi does a great job of helping her students find their own voice and style when teaching and provides many opportunities for students to practice teaching. Each student is assigned a mentor, someone who has completed a previous teacher training course, to give advice and opportunities to practice teaching. Cassi is very thoughtful about mentor/mentee assignments to be sure that the pair have things in common, which really helps build a connection and creates a sense of community in the studio. Now that the training is over, I can say that not only did the training help me to reach my original goals of learning more about yoga and deepening my practice, but it also helped me to realize that perhaps, teaching some classes is something I would enjoy despite my initial reluctance. Whether you are someone who intends to teach yoga part time, full time, or not at all, the teacher training at Mission Hill Yoga is a great way to learn more about the fascinating practice of yoga. You might even discover things you never expected to find!”

“What an amazing Teacher Training experience at Mission Hill Yoga. Cassi teaches an in-depth level to the practice of Yoga. Breathe, Flow, Mindfulness and Meditation. Yes. You do hear these terms during your regular weekly classes. However, these terms, and much, much more, Cassi emphasizes throughout the course.
Cassi’s knowledge, professionalism, energy, patience, and encouragement has been unwavering. It is so defining as soon as you walk into the studio – the warmth, support and spirit exudes in the space. That energy flows within the students during the regular classes as well as Teacher Training.
No matter where you are in life, it is never too late to learn more even if you decide not to teach. For me, meditating daily (sometimes more than once a day) is now part of my routine and has been very uplifting.
When you sign up for Teacher Training, be prepared to flow, sweat, learn, and enjoy”

“Being a part of the 2020 MHY Teacher Training cohort was deeply meaningful and unique! Our cohort was the first cohort impacted by COVID-19. This meant that the traditional manner in which training had been offered had to be adjusted to ensure the safety of training participants. Cassandra went above and beyond her care and attention to creating a safe space for us to learn, and deepen our personal connection to yoga. In addition to masks being worn during our time in training, Cassandra created sanitized pods and added air filters throughout the learning space.

The physical and emotional safety I felt while in the space was profound, and I am convinced that this contributed to the overall quality in my teacher training experience. Interestingly enough, while our training schedule, plans, and environment may have been impacted by the reality of us being in the middle of a public health crisis, there was never a point at which I felt that my training experience was being adversely impacted or compromised. If anything, there were certain points throughout my journey where I felt this challenge, in many ways, enhanced the quality of the training and the relationships I was creating during the program.

While the training was an intensive 10 week course, the pace of the instruction was not overwhelming. The time and sequence of subjects throughout the training was intentionally structured in a way where I was able to fully engage and retain the information without feeling rushed. My time in training was just what I needed to remain connected and grounded during these times. I am beyond grateful for the experience and would do it all again in a heartbeat! Thanks so much Cassandra!”

“Yoga teacher training at Mission Hill Yoga, with Cassandra Foster, was a journey that I would not trade for anything. This 200-hours flew by, and helped uplift my heart and spirit during the darkest moments of 2020. Like many others, I never envisioned myself wanting to be a yoga teacher, and signed up for the experience to deepen my own practice and learn more about the asana that I love. I cannot overstate how much this experience changed my life; and since completing the training I have found myself considering teaching, as a way to share this new found appreciation and passion. Further, I have always been interested in the asana practice, but this experience really pushed me to explore greater boundaries of myself through meditation and dharma, and for this I feel grateful. The small group environment made for a truly special space to learn from Cassandra as well as my fellow yogis. This type of learning allowed us to experiment, get creative, and push one another outside of our comfort zones, which enabled me to immerse myself into a life changing practice. Being guided by Cassandra’s wisdom and passion was truly a gift that I will be forever thankful for experiencing. Honestly, when I signed up I never expected this training to be one of the pivotal moments of my life, but it was; and I look forward to continued mentorship and guidance from Cassandra and my fellow YTT classmates.”

“Yoga teacher training with Cassi at Mission Hill Yoga was just the kind of training I was hoping for. Given the time and financial commitment, I was hesitant to take that step in my yoga journey, but I am so glad I did. Cassi curates the training to be supportive and to fit the needs of her students by bringing in outside experts, setting each student up with a mentor, and covering a solid base of training content. The best part for me was that the training was small and intimate, so I really felt like I had ample opportunity to learn, practice, and ask questions. Cassi has so much knowledge in the more technical aspects of asana and sequencing but also in the other aspects of yoga as well, specifically meditation and pranayama. After completing training, I really feel like I have a support system in Cassi and community at Mission Hill Yoga.”

“I went through yoga teacher training to find and build a community. Relatively new to Boston, I struggled to find and meet like minded people, and began to attend regular yoga classes to help combat the stressors of everyday life. I am also a wellness nerd and obsessed with learning more about the human condition and our mental, emotional and physical states and how to optimize overall wellbeing. I strongly believe in taking care of yourself from a holistic perspective - incorporating mind, body and soul and I want to be of service to others to help provide the information, tools and space for them to evolve and grow in any one or all of those areas. I have found the empowering and transformative art of yoga to be healing and beneficial in so many ways, and I want to help provide that to my students in a way that meets them where they are. My yoga teacher training experience at Mission Hill Yoga provided me with the education, support, confidence and community to embark on this journey and I couldn’t be more grateful!!”

“I had always flirted with the idea of going through a yoga teacher training but naturally came up with some excuse to push it to the future. Until the future suddenly became the present! Mission Hill Yoga has created an opportunity for yogis of all levels to understand the concepts and develop the skills necessary to become a strong yoga instructor. Throughout this 200 hour training, I learned much about the history of the practice, the importance of anatomy, and the actual approach to teaching and sequencing. It was a lot of information. It was a lot of time. It was a huge commitment. I would do it again in a heartbeat. However the title “teacher training” may be a bit of a misnomer, as the depth of this experience is more than just learning how to teach. It is an opportunity to look within yourself and discover the endless possibilities that only yoga can provide. Under the guidance of Cassi, students develop an awareness of their energy and an awakening of their voice. Her bounty of knowledge, intense focus, and endless energy in addition to her commitment to each of her students, provides an atmosphere that fosters growth, not only in yoga, but in life. I had no idea what to expect, but any expectations I had were exceeded.”

“I’m really glad that I took YTT. My goal was to learn more about yoga philosophy and develop a self-practice versus starting a yoga career. It was eye-opening to learn the logistics of creating a sequence and finding the appropriate cues to better the alignment and deepen the pose. I am more mindful and appreciative of these aspects in class. I also enjoyed learning about meditation and the benefits of starting my own practice. I would recommend YTT for anyone looking to deepen their understanding of yoga or build community at the studio.”

“Yoga teacher training at Mission Hill changed my life. I’m not sure I can adequately put into words what it has taught me, but I’ll certainly try. Cassi has a passion for Yoga. It’s evident in the way she teaches, practices, and lives by the Dharma. Yoga, for many, is just Asana but in teacher training, you learn about much more than Asana. It’s not just the physicality of the Asana practice but the INTENTION behind each Asana. I learned I was doing things as basic as downward facing dog incorrectly and without intention. Even if you never teach another person, this teacher training will significantly impact and progress your own self-practice. I learned mindfulness because in order for me to teach my students mindfulness I had to have a healthy relationship with my own mind. We were taught both Buddhist and Hindu philosophy, although Cassi is a predominantly Buddhist based teacher. We also learned about many forms of meditation and were assigned readings that broadened our scope. One of my favorite weekends of training was the assists weekend. I realized I had a gift that weekend. A gift to lift and help heal those around me with my hands and energy. I made someone feel safe with my touch and that’s a moment I will forever cherish. I love this training because Cassi took into consideration each of our modes of learning to make the information as accessible to everyone as possible. I met some of the strongest women during my training and we honestly have become family, sangha. This teacher training has significantly helped me heal my body, my mind, and my spirit.”

“I got hooked on Cassi’s yoga classes in 2016 at various studios around the city. Once she opened her own space, my practice became regular and I knew that I wanted to deepen my practice and knowledge more. Yoga Teacher Training with Cassi at Mission Hill Yoga is truly transformative whether you plan to teach immediately after completing the program, or you want to go deeper with your own practice. I was steered towards Cassi’s MHY not only because I love her teaching style, but also because the class size was intimate and not intimidating. You get out of it what you put into it. It’s not always easy- both physically and mentally- but it was a beautiful experience and I can’t thank myself enough for this experience and gift I provided myself. Cassi is caring and compassionate, and ensures you are equipped with the knowledge and experience to leave the training ready to teach and share your love of yoga with others. ”

“Thank you to the entire Mission Hill Family for the wonderful 200 Hour Yoga Teacher Training. To say it’s been an honor to practice with all of you would be an understatement. The encouragement, uplifting and empowerment that you gave will never be forgotten and has transformed me as a person from the inside out. This Yoga Teacher Training has taught me that I have so much more to learn..... Cassi is a knowledgeable, informed and terrific yoga teacher and instructor. She took the time to understand the pose from my perspective on the mat, something that is very rare in today’s cookie-cutter yoga environment.

What Cassi provided was more than just a yoga training, she managed to instill confidence in me I didn’t realize existed. She believed in my abilities even when I could not see them providing just the right amount of faith until I could catch up. She is perhaps one of the more patient and balanced people. She brought this 100% to each and every class consistently. I highly recommend this training to anyone, Cassi will lead you into a deeper understanding of yoga and you will perhaps most likely leave with a profound awareness of who you are within.”

“I signed up for yoga teacher training to enhance my knowledge and practice for yoga with the possibility of teaching. Cassi delivered, and then some. Her vast knowledge and experience translated well both as a teacher in her classes and in the training. The space she creates for her students to learn and be open is one that can’t be replicated elsewhere. Thank you, Cassi, I’m so happy I took your training and would do it again!”

“Like most of the students in my small yoga teacher training class, I signed up for the class with no intention of teaching after and not knowing what to expect. With Cassandra as our instructor, I gained so much knowledge about the history and theory of yoga. I was able to deepen my practice. Most surprisingly I found myself wanting to teach and having the confidence and the skills to do so right away. I picked up my own regular class teaching at a studio about two months later, and have been able to continue to grow as an instructor since then with the solid foundation provided in teacher training with Cassi. I would highly recommend signing up for training with Cassi. She is knowledgeable and her practice is inspiring.”

“Cassandra is an amazing teacher! Her wealth of knowledge and generosity of spirit has had a positive influence on me. Through 200-hour Teacher Training with Cassi, I learned to open my mind and heart and live more mindfully. Initially signing up to deepen my understanding of Yoga and its teachings, Cassi’s preceptorship enabled me to become a yoga instructor. Her deep respect for yoga practice and its philosophy shines through to all she meets. Wise beyond her years, Cassi “gets it”. I am grateful to have studied under Cassandra Foster and will continue to learn and practice under her mentorship.”

“I highly recommend taking Cassandra Foster’s 200 hour YTT classes! After regularly practicing yoga for 3+ years, I secretly wanted to become a yoga teacher, but did not think I was experienced enough. When I learned about Cassi’s training and discussed my yoga practice with her, she immediately quelled my fears. The anatomy, history, alignment, and asana classes were all thoughtfully presented. Questions were always welcomed and the knowledge learned was invaluable. My fellow classmates were always encouraging, positive, and supportive. I started teaching three weeks after completing the YTT, and thanks to Cassi, I have the confidence to share my practice and enlighten others to my passion for yoga.”

“I am a busy mom of 2, who has practiced yoga on and off for 15 years. In recent years, the idea of a YTT had intriuged me. I was interested in learning more about the “why” behind the poses and how to deepen and improve my overall practice and flexibility. I signed up to take Cassi’s training as I had heard amazing things about her as an instructor (and to this day, after all the yoga instructors I’ve had, she is still, by far, my favorite). YTT was the first thing I’d done for myself in what felt like a long time and my practice was definitely rusty. Cassi went over the history and philosophy of yoga, taught us all about meditation (wait until she teaches you yoga nidra!), the importance of form and alignment within poses, the significance of adjusting and how to teach a class. She gave us crucial tips on teaching and brought in guests to assist with complex topics. Overall, YTT with Cassi was a wonderful experience that exceeded all expectations I had. I now often teach friends and share my newfound knowledge with them. I still miss the days of getting up when it was still dark to meet Cassi and my co-trainees in the yoga studio. It’s a time I’ll always hold dear to my heart and am ever so grateful for.”

“After having had a regular yoga practice for 3-4 years I knew I wanted to learn more. The classes I had taken with Cassi had shown her to be very knowledgeable and sincere in her practice. Her guidance in class clearly demonstrated her innate ability to ‘read’ the body and assist in a way that allowed me to feel stronger in poses and enhance my own practice. Thus, although the YTT options in Boston are extensive, I really felt Cassi could help with what I was looking for. Embarking on the 200-hr teacher training with her was something I will never regret. The whole program delivered much more than what I could have expected. Each element was outlined and discussed in an engaging and informative way and has truly transformed my practice. My intention was never to teach, yet the approach instilled an understanding that has allowed me to develop a meaningful and fulfilling individual practice. I still practice with Cassi and she never fails to inspire.”

“If you want to transform your mind, body, and soul then get certified with Cassi. I have been practicing off and on since 2002 and it took me some time to decide to take my practice to the next level. I researched and practiced with various instructors and studios. I chose Cassi because of her ability to teach to all fitness and experience levels, the structure of her course, her style and spirit, and the work-life balance the course allowed. My intent on starting this program was to further my personal practice. Through the program, I have discovered that I enjoy assisting. My favorite is the spa class! Not only do I get to utilize the skills I have learned but also help others relax and de-stress. This program has made me stronger mentally and physically while calming me at the same time. I would highly recommend Cassi. An added benefit is the lasting community and friendships I have made. My only regret is that I didn’t do it sooner. ”
